Program required me to change the Windows decimal symbol from , to . in the control panel before it would accept my carrier version. After that, worked fine! Didn't even have to restart. Thank you very much!

Yeah, Windows 7 with the latest version of iTunes. Clicking either .ispw or .ipcc and then "Open" yields what I assume to be an empty folder. No files appear and the message says "No items match you search"

So i managed to change my carrier logo but I couldn't restore it back to the default. I then tried creating another to get a new original .pcc and still couldn't restore from that one. Tried rebooting and all.
